2.1 Introduction This chapter covers how to test the operation of the Rad-8 and how to properly clean the Rad-8 Pulse Oximeter, how to recharge and replace the batteries, and how to obtain service under normal operation. No internal adjustment or recalibration is required. Service should be performed by qualified service personnel only. Safety checks should be performed at regular intervals or in accordance with local and governmental regulations. Note:

Opening or repairing the Rad-8 Pulse Oximeter will void the Masimo warranty. Products that require repair while under warranty should always be returned to Masimo for warranty service.

WARNING: ELECTRICAL SHOCK AND FLAMMABILITY HAZARD. ALWAYS TURN THE UNIT OFF AND DISCONNECT THE POWER CORD FROM THE BACK OF THE UNIT FOR ANY MAINTENANCE, SUCH AS CLEANING, DISASSEMBLY OR ASSEMBLY.

2.2 Cleaning The outer surface of the Rad-8 Pulse Oximeter can be cleaned with a soft cloth dampened with a mild detergent and warm water solution. Do not allow liquids to enter the interior of the instrument. The outer surface of the instrument can also be wiped down using the following solvents: Cidex Plus (3.4% Glutaraldehyde), 10% Bleach, and 70% Isopropyl Alcohol. 2.2.1 To clean the display panel use a cotton swab moistened with the cleaning solvent and gently wipe the panel. 2.2.2

To clean the outer surface of the Rad-8 Pulse Oximeter, use a soft cloth moistened with cleaning solvent. Do not allow liquids to enter the interior of the instrument.

2.2.3

To decontaminate unit, refer to Section 7.1.2.

4.1

Overview

4.1.1

To test the performance of the Rad-8 Pulse Oximeter following repairs or during routine maintenance, follow the procedure outlined in this section. If the Rad-8 Pulse Oximeter fails any of the described tests, discontinue its use and correct the problem before returning the unit back to the user.

4.2

Power-On Self-Test

4.2.1

Plug the Rad-8 Pulse Oximeter into an AC power source with no cables or sensors attached, turn the monitor on with the “Power Button”. For about 2 seconds all available LEDs are illuminated and a brief beep tone sounds. The unit will then cycle through Saturation and Pulse alarm limits on the LED display.

4.2.2

After this initialization “boot” cycle, the No Sensor, Alarm Suspend Mode LED indicator’s will light. Also, the %SpO2 and BPM monitoring display will indicate “no” “sen”. The Rad-8 Pulse Oximeter is ready to begin normal operation.

4.2.3

Turn power off and then back on as many times as necessary to verify this Power-On cycle.

4.3

Key Press Button Test

4.3.1

With the exception of the Power Button, press each soft key button and verify that the Rad-8 Pulse Oximeter acknowledges

4.5.2

Press the UP arrow button and cycle through the four different volume levels. Make sure the tone does not have a harsh or raspy tone due to the speaker rattling in the plastic housing. The tone heard should be louder with each press. Press the DOWN arrow button and cycle through the different volume levels. The tone heard should be quieter with each press. Verify both speakers are working.

4.5.3

Return the volume to the factory default level 3.

4.6

Alarm Limit Test

4.6.1

With the monitor turned on, depress the ALARM LIMITS button and enter alarm menu. Change the High Saturation Alarm parameter to a value two points below the currently selected value, and accept the change by pressing the Enter button.

4.6.2

Verify that the newly set parameter is shown on the Saturation Alarm Limit Display.

4.6.3

Return the High Saturation Alarm parameter to its original setting and accept the change by pressing the Enter button.
